APES Water Pollutants
Terms in this set (15)
Nonchemical water pollution that occurs when human activities cause a substantial change in the temperature of water
Cholera, Typhoid fever, Hepatitis A, many diarrheal diseases caused by many viruses and microorganism (often coming from human or animal waste)
Disease causing organisms
E. coli (Fecal coliform bacteria)
What is the indicator species to tell if any disease causing organisms are present?
This is rarely found in natural sources of drinking water and it affects fetuses, infants and children the most. It can cause brain and nervous system damage, kidney damage, and learning disabilities from brain damage.
From corroded lead pipes, paint (Mostly found in older buildings)
How does lead get into water systems?
This is found naturally in Earth's crust and can dissolve into groundwater. Mining can contribute high levels of this in water. This will cause cancer in the skin, lungs, kidneys, and bladder. Very high concentrations of this is found in the West and Midwest, and we can get rid of it by distillation, as chlorine cannot remove it
This is a heavy metal found in nature, and in contaminates water through burning coal or garbage. Inorganic ________ is relatively harmless but when bacteria convert it is becomes hazardous and can damage the central nervous system
These can be harmful to unintended victims especially when built up in water systems (DDT)
Pharmaceuticals and Hormones
When you take ____________________________ and then your waste ends up in the water those can really be bad for the water ecosystems
Natural seeps from oil deposits at the ocean floor, Runoff from land, discharge from ships, Oil spills
How does oil end up in the water?
It is non-degradable, and exposure to sunlight will cause it to break apart into smaller pieces which then accumulate in gyres, animals ingest
What is the problem with plastic?
The Great Pacific Trash Vortex, located in the South Pacific gyre
Where is the largest collection of plastic pollution?
Any relatively large solid material (rocks, gravel, sand, solid human and animal waste, twigs, cans, etc.) and Fats, Oils, or grease (FOG)
What components of sewage does primary treatment removal target?
Particulates and other substances removed from wastewater during primary and secondary treatment create a significant amount of solid material which must then be disposed of elsewhere.
Explain how sewage treatment plants create a solid waste problem?
Natural and Anthropogenic
What are the two categories of water pollution?
